Why is Kefir tangy, seem slightly carbonated, or bubbly?
Since our Kefir contains live and active cultures, there will be a small, varying degree of effervescence. In addition, the kefir consistency can vary depending on the amount of time passed after it was produced. All this means is that the probiotic kefir cultures are active and working. This does not mean the product is spoiled in any way. Spoiled kefir will resemble spoiled milk and have a very pungent odor.
